[0002] High-speed cutting has become a crucial aspect of machining and manufacturing technology. HSK tool holders are currently widely used in high-speed cutting.

[0003] Most HSK tool holders on the market currently use steel balls. The four steel balls are pushed by the tail of the tool holder. Under the restriction of the steel ball holes in the bracket, the inclined plane allows the push block to overcome the spring force and move the push block to one side of the cylinder, so that the steel balls move towards the center. After the HSK tool holder is installed in place, the push block, under the action of the spring, causes the steel balls to pop out and lock the tool holder, preventing the tool holder from falling out of the tool holder.

[0004] However, since the pusher protrudes from the tail of the tool holder, this design requires sufficient operating space for the pusher, which not only increases the overall space occupied, but may also limit the use of the tool holder in some compact spaces. In addition, key components such as the pusher and spring are located at the tail of the tool holder, making them more susceptible to interference and potential damage from the external environment, resulting in the tool holder not being able to be removed properly.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0033] As Figs. 1 to 4 The tool sleeve structure suitable for HSK tool shank of chain tool magazine shown in the figure, including: main part 1, guide shaft 2, loose tool shaft 3 and lock tool block 4, the inside of main part 1 is provided with through hole for placing tool shank;Guide shaft 2 is arranged along the radial direction of main part 1;Loose tool shaft 3 is arranged parallel to guide shaft 2 and located in the same section;Lock tool block 4 is arranged in the through hole, located at the tail end, slidingly arranged on guide shaft 2 and loose tool shaft 3, and a lock tool boss 41 is arranged at the end of the tool shank, which is in contact with the inner ring surface of the tool shank;

[0034] Wherein, the end of loose tool shaft 3 extending out of main part 1 is provided with end boss 31, and first elastic element 5 is arranged at the outer cylindrical surface of end boss 31 and main part 1;

[0035] The shaft section of loose tool shaft 3 located in the through hole is sequentially provided with sliding shaft section 32 and mounting shaft section 33 in the direction away from end boss 31 along the axial direction, the diameter of sliding shaft section 32 is greater than that of mounting shaft section 33, lock tool block 4 is slidingly arranged on sliding shaft section 32, and second elastic element 6 is sleeved on mounting shaft section 33;

[0036] The end of loose tool shaft 3 away from end boss 31 is provided with lock nut 7.

[0037] When loosening the tool, the axial force is applied to loose tool shaft 3, so that end boss 31 compresses first elastic element 5, when the stepped surface of sliding shaft section 32 and mounting shaft section 33 is in contact with second elastic element 6, at this time, loose tool shaft 3 continuously compresses second elastic element 6, and lock tool block 4 loses the thrust force of second elastic element 6, with the tool shank being pulled outwards, the inclined surface of tool shank moves lock tool block 4 along the axial direction of guide shaft 2 towards the central axis of main part 1, until the tool shank is separated from the lock tool opening;

[0038] When locking the tool, after the tool shank is inserted into main part 1, the thrust force on loose tool shaft 3 is released, under the double action of first elastic element 5 and second elastic element 6, loose tool shaft 3 is quickly reset, and the lock tool opening is locked to the tool shank by the reaction force of second elastic element 6.

[0039] In the utility model, by setting guide shaft 2, loose tool shaft 3 and lock tool block 4, combined with first elastic element 5 and second elastic element 6, the locking and releasing of tool shank are realized, and lock tool block 4 and second elastic element 6 are hidden in the inside of tool sleeve, so that the tool sleeve is more compact, is more suitable for use in limited space, further reduces the direct contact of them with external environment, and prolongs the service life of tool sleeve.

[0040] In order to limit the rotation of the tool in the circumferential direction, the tool sleeve further comprises positioning pin 8, which is arranged in the circumferential direction of main part 1 and embedded in the positioning groove of tool shank.

[0041] In the preferred embodiment of the utility model, the locking tool boss 41 is arranged obliquely with the contact surface of the inner ring surface of the tool handle. When the step surface of the tool releasing shaft 3 acts on the second elastic member 6 and makes it in the compressed state, the locking tool block 4 loses the thrust of the second elastic member 6, at this time, the oblique contact surface makes the locking tool boss 41 be able to slide off the inner ring surface of the tool handle more smoothly.

[0042] When locking the tool, the locking tool block 4 is in the compressed state, one end of the second elastic member 6 abuts on the locking tool block 4, and the other end abuts on the inner wall of the main body part 1, preferably, the inner wall of the main body part 1 is provided with an embedded groove 11 corresponding to the second elastic member 6.

[0043] In the tool locking state, one end of the second elastic member 6 abuts on the locking tool block 4, and the other end abuts on the bottom surface of the embedded groove 11, and in the tool releasing state, the tool releasing shaft 3 moves along the axial direction and presses the second elastic member 6 into the embedded groove 11, compared with the abutment of the cylindrical surface, the embedded groove 11 provides a planar contact surface, so that the end pressure distribution of the second elastic member 6 is uniform, which helps to reduce local wear and stress concentration and improve the durability and reliability of the spring.

[0044] In the preferred scheme, the first elastic member 5 adopts a disc spring structure. The disc spring plays a buffering role in the tool releasing process, reduces the impact on mechanical parts caused by sudden release of locking force, helps to protect the tool releasing shaft 3, the locking tool block 4 and other related parts from damage, and prolongs the service life of the overall structure. And by controlling the compression degree of the disc spring, the moving distance of the tool releasing shaft 3 can be further accurately controlled, so as to ensure that the locking tool block 4 can be unlocked in a predetermined manner.

[0045] In the preferred scheme, the second elastic member 6 adopts a spring structure. In the tool locking process, the spring provides a stable thrust force for the locking tool block 4, ensuring that the tool handle is firmly locked in the main body part 1, which helps to prevent the tool from falling off due to vibration or impact during cutting, improving the stability and safety of machining. When used in combination with the disc spring, the spring structure can work cooperatively, the disc spring provides a quick reset force, and the spring provides a stable thrust force, realizing an efficient tool locking and releasing process.

[0046] In the utility model, the position of the locking tool block 4 between the guide shaft 2 and the tool releasing shaft 3 is provided with a lug 42. When the second elastic member 6 acts on the locking tool block 4 to lock the tool, the boss is close to the lower part of the guide shaft 2, keeps the annular gap between the guide shaft 2 and the sliding hole of the locking tool block 4 uniform, and effectively avoids the inclination of the locking tool block 4.

[0047] As a preferred solution, the mounting shaft section 33 is connected to the sliding shaft section 32 using a threaded structure. The split design using threaded connection simplifies the maintenance and replacement process of the knife loosening shaft 3. When one of the shaft sections is worn or damaged, it can be replaced individually without the need to replace the entire knife loosening shaft 3. This reduces maintenance costs and reduces downtime, improving the overall availability and production efficiency of the equipment.

[0048] In the preferred embodiment of the utility model, the inner hole of the lock block 4 through which the knife loosening shaft 3 passes is located at one end of the second elastic member 6 and extends inward to form a limiting edge 43. When the knife loosening shaft 3 moves to abut against the limiting edge 43, it can drive the lock block 4 to move synchronously. By controlling the movement of the knife loosening shaft 3, the lock block 4 is pushed to slide, thereby easily realizing the locking and releasing of the handle, effectively avoiding the wear of the lock convex 41 and the handle, and effectively ensuring the positioning accuracy and reliability of the lock.

[0049] Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
